Which of the following cations is isoelectronic with argon? 1.potassium ion 2.calcium ion 3.scandium ion 4.All of these 5.None of these
Option 1 is correct because potassium ions in argon contain 18 electrons. Thus, there are 18 isoelectronic in all that are present in Ar for K+. The electrical arrangement of these two ions is the same as that of Ar.
K+ and Cl ions are hence isoelectronic with Ar. Argon is isoelectronic with potassium ions that have a positive charge. For an ion with a -1 charge to become isoelectronic with argon, it would only have needed to gain 1 electron. Chlorine must have been present there.
Similar to the previous element, the next one can create a monovalent cation by losing one electron and isoelectronizing with argon. These include the potassium cation, K+, the chloride anion, Cl, and the sulphide anion, S2. Isoelectronic ions are said to have the same number of protons and electrons.

why should a magnesium ribbon be cleaned before burning in air?
The decomposition of a single compound at 349 K has a rate constant of 4.10 x 10-3 M s1. If the initial
concentration of the reactant is 1.304 M, what is the concentration of the reactant after 90.45 seconds?
(the answer should be entered with 3 significant figures; do not enter units; give answer in normal
notation-examples include 1.23 and 12.3 and 120. and -123)
Selected Answer:
Correct Answer:
0.933
0.933 ±1%
Answer: To solve this problem, you can use the first-order rate equation, which is given by:
[reactant] = [reactant]0 * e^(-k*t)
where [reactant] is the concentration of the reactant at time t, [reactant]0 is the initial concentration of the reactant, k is the rate constant, and t is the time.
Plugging in the given values, we get:
[reactant] = 1.304 M * e^(-4.10 x 10^-3 M s^-1 * 90.45 s)
= 1.304 M * e^(-0.0366)
= 1.304 M * 0.933
= 1.21 M
To express the answer with 3 significant figures, you can round the answer to 1.21 M. Therefore, the concentration of the reactant after 90.45 seconds is 0.933 ± 1%.

C
A covalent bond occurs when atoms share one or more pairs of electrons to form a stable molecule. The difference in electronegativity between two atoms plays a role in determining the type of bond formed between them. In general, covalent bonds are formed between atoms with similar electronegativities.
A covalent bond can form between two atoms if the electronegativity difference between them is less than 1.7. However, the size of the atoms is not the determining factor in covalent bond formation. Instead, the atomic electron distribution and electron affinity are very important.
In general, covalent bonding is a key process in chemistry that allows atoms to form stable bonds with each other. It is a key factor in determining the properties of various chemical compounds such as gases, liquids and solids.

Benzene is a carbon and hydrogen compound with aromatic properties. The chemical formula for benzoene is C6H6.To determine the number of sigma bonds in this, we can create the skeletal structure using only sigma bond representations.
Let's show the structure of benzene.
As can be seen, there are six C-H bonds and six C-C bonds.
We may therefore say that benzene has a total of 12 sigma bonds in it.
When we look at the structure of benzene, we can see that it has three C=C bonds.
There are consequently 3 pi bonds and 12 sigma bonds. As a result, benzene contains 15 covalent bonds.
Since benzene has 12 and 3 sigma and pi bonds, respectively, the correct answer is that it does.

What is the sp
of the salt at 25 °C?
AB(s)↽−−⇀A+(aq)+B−(aq)
Correct task : At 25°C, only 0.0140 mol of the generic salt AB3 is soluble in 1.00 L of water. What is the Ksp of this salt at 25°C.
Solution:
When the salt dissolves, it dissociates as follows:
AB3 --> A3+ + 3B⁻
--S--------S-------3S--
The molar solubility (S) is the number of moles that can dissolve in 1 L of solution.
Molar solubility of salt is (0.0140 mol) / (1.00 L) = 0.0140 mol/L.
According to the dissociation equation:
Solubility of A3+ is 0.0140 mol/L and solubility of B⁻ is 3×0.0140 mol= 0.0420 mol/L.
[A3+] = 0.0140 mol/L.
[B⁻] = 0.0420 mol/L.
Ksp is the solubility product constant and calculated as follows:
Ksp(AB3) = [A3+] × [B⁻]3
Ksp(AB3) = [0.0140] × [0.0420]3
Ksp(AB3) = 10.37×10-7.
Ksp of this salt is 1.04×10-6.

Powerful molecular forces Intermolecular forces that are weak Answer bank High surface tension, high viscosity, high vapor pressure, and high boiling point.
A liquid's resistance to flowing is determined by its viscosity. Viscosity is a measure of how strongly intermolecular forces are present in a liquid. All four parameters—boiling point, melting temperature, surface tension, and viscosity—decline significantly. The substance's vapor pressure rises as a result of the molecules' easy escape due to weak forces. In a closed container, vapor pressure develops when liquid molecules have enough kinetic energy to break free from the intermolecular interactions and transform into a gas. The magnitude of intermolecular forces has an inverse relationship with vapor pressure.

suppose of ammonium sulfate is dissolved in of a aqueous solution of sodium chromate. calculate the final molarity of ammonium cation in the solution. you can assume the volume of the solution doesn't change when the ammonium sulfate is dissolved in it. round your answer to significant digits.
The final molarity of the ammonium cation in the solution is 0.066M.
Firstly, we need to calculate the number of moles of ammonium sulfate:
No of moles = mass(g)/molar mass
No of moles = 2.57/132.14
No of moles = 0.0195 mol
When ammonium sulfate dissolves in sodium chromate, the following reaction will take place:
(NH₄)₂SO₄ + Na₂CrO₄ ------> (NH₄)₂CrO₄ + Na₂SO₄
No of Moles of sodium chromate = molarity x volume
= 66 x 0.200
No of moles of Sodium Chromate = 0.0132 mol
According to the reaction, 1 mol of sodium chromate produces 1 mol of ammonium chromate.
In this reaction, the sodium chromate amount is less than ammonium sulfate.
It can be concluded that Sodium chromate is a limiting reagent.
Therefore 0.0134 mol of ammonium cation is present in the resulting solution.
Molarity of ammonium cation = 0.0134 mol / 0.2 L
Molarity = 0.066 M
Therefore, 0.066M is the Molarity of the ammonium cation.

Radioisotopic dating estimates the age of objects based on the fact that the half-life of any radioactive isotope is _____.a fixed value

The fundamental idea behind radiometric dating is that by comparing an isotope's presence in a sample to its abundance on Earth and its known half-life (rate of decay), you may determine the sample's age.

It is also used to refer to molarity, quantity concentration, or substance concentration. The most common unit used in chemistry to express molarity is the number of moles per liter, represented by the unit sign mol/L or mol/dm3 in SI units. One molar, or 1 M, of a solution's concentration is defined as one mol/L. Molarity is a unit of concentration used to describe chemical solutions (M). It is the number of moles of the solute in one liter of solution. This is not the same as the liters of solvent, to be clear (a common mistake). Despite being a useful unit, molarity has one fundamental flaw. Because temperature affects a solution's volume, it does not remain constant when it varies.
